Howdy gang. I have a friend who is really into Cigars, and he asked me if I could turn a big fancy ash tray. I have no problems as far as turning it, but I hate to make it and worry about every detail and it gets all burnt up the first time it gets used. I thought about just lining it with a convetional glass ashtray, but I was wondering if anybody knows of any heat/fire resistant finishes or resins I could coat the inside with. I remember back when I was younger a lot of people had wooden ashtrays, but don't see them anymore since smoking has become the devil in the last 20 years. Anyways, if anybody knows of a product or proccess I appreciate it.
 
wooden ashtray

Remember pipes for smoking tobacco? These were usually made out of briar which is easy to turn and finish while the inside will get charred like what pipes did after some usage. So finish the outside and put a texture on the inside that might look like metal after it is used (darkened) after awhile.

Bernie-

After you have turned the piece, you might try and get a thin piece of copper and hammer it into shape of the bowl of the ash tray. The smoker then can lift out the medal part and empty.

I would agree with Bernie. I know you put fire retardant in a finish but that won't stop it from turning yellow or getting charred. If you don't put glass in the ashtray you could hammer some thin copper into the depression. I remember making an ashtray that way when I was in middle school only we were simply making the copper ashtray.
 
Sodium silicate (aka water glass) might be suitable. Google [sodium silicate heat resistance] and [sodium silicate where to buy]. I'm not sure how runny it is, and you'd best experiment (e.g. number of coats) on some scrap before committing to final production.

OTOH, spun metal could be an interesting addition to your turning repertoire.
